The main functions of drilling mud additives

Drilling mud additives are mainly chemical substances added to the mud during the drilling process to improve mud performance, improve drilling efficiency, maintain wellbore stability. The functions of drilling mud additives mainly include the following aspects:

Viscosity control: Adding mud additives can control the viscosity of the mud, making it suitable for drilling exploratory wells smoothly recovering broken rock debris. During the drilling process, the mud needs to have a certain viscosity in order to transport drilling cuttings rock fragments in a suspended state, deposit them in the drilling waste pool for further recovery treatment.

Suspendability: Mud additives can improve the suspension ability of mud to rock cuttings, drilling cuttings, other impurities, reducing the degree of wellbore wear.

Gel breaker: Mud additives have a gel breaking effect, which can reduce the adhesion between the mud the wellbore wall, avoiding mud adhering to the wellbore wall forming a mud ring that can block the well affect drilling speed.

Defoamer: Mud additives can defoamer reduce foam, preventing the mud reducing its ability due to the influence of bubbles.

Sand resistance performance: Mud additives can improve the adhesion of mud to formation solids, strengthen wellbore support, protect the wellbore erosion collapse in the wellbore.

Stabilizer: Mud additives can increase the adhesion of clay in the mud, increase the adhesion of the mud in the wellbore, improve the stability of the formation, control the mud performance during the drilling process.

Anti expansion agent: Mud additives can prevent the expansion of mud control the size of the wellbore the rate of lifting drilling cuttings. This is very important for the drilling process because while controlling the wellbore, it can also control the stability of the wellbore.

In summary, drilling mud additives have various functions such as controlling mud performance, improving drilling efficiency, maintaining wellbore stability. Different mud additives can meet different drilling objectives wellbore requirements, thereby improving the efficiency cost-effectiveness of drilling operations.
